I want to graph the change in the number of bytes or lines in a file (very large syslog files) since the last poll. The files are rotated every night back to zero.
I have a script which is returning the data, my question is what DS type to store it with. None of guage, counter, absolute or derive seem quite right. Reading the docs I came up with 2 possibilities - Using GUAGE with a CDEF that subtracts LAST - Using DERVICE with a CDEF that multiplies it by the polling interval. Are either of these correct or is there a more efficient way?
